2926.90.19.00 - N,N-Bis(2-cyanoethyl) aniline; and 2,6-Difluorobenzonitrile

This HTS classification, **2926.90.19.00**, specifically covers certain aromatic nitrile-function compounds that are not otherwise enumerated. The primary substances falling under this subheading are N,N-Bis(2-cyanoethyl) aniline and 2,6-Difluorobenzonitrile. These are distinct organic chemical compounds characterized by the presence of a nitrile group (-CN) attached to an aromatic ring system, or in the case of N,N-Bis(2-cyanoethyl) aniline, where the nitrile groups are attached to alkyl chains that are in turn attached to an aniline moiety.

This subheading serves as a residual category for aromatic nitriles within the broader "Other" group of nitrile-function compounds. It is distinguished from its sibling categories by the specific chemical structures and applications of the listed compounds. For instance, it differs from subheadings covering simpler aromatic nitriles like benzonitrile (2926.90.08.00) or specific substituted benzonitriles such as p-chlorobenzonitrile (2926.90.14.00). It also excludes compounds like 2-Cyano-4-nitroaniline (2926.90.01.00) or the various dichlorobenzonitriles, each of which are classified under their own distinct HTS codes due to their unique properties and common trade volumes.

As **2926.90.19.00** represents a leaf node within the HTS database, it does not have further subcategories. Therefore, the focus for classification under this heading is on the precise identification of the imported or exported chemical substance and confirming that it precisely matches the chemical description of N,N-Bis(2-cyanoethyl) aniline or 2,6-Difluorobenzonitrile, and that it is not more specifically provided for elsewhere in the tariff schedule. This ensures accurate duty assessment and trade statistics for these specialized organic chemicals.
